Q: What are rocker arm stoppers? Why buy them?
A: Rocker arm stoppers are components that mount in your valve train to help the rocker arms to stay in alignment and prevent the rockers from floating. On rocker arm equipped vehicles, high engine revs can often cause the rocker arms to move around, which will increase wear on the valve train and reduce engine power and smoothness. With rocker arm stoppers you can keep your rocker arms in check to ensure that they are doing their job and not wandering out of alignment. This modification is inexpensive and is great insurance for those who like to take their engines close to redline. Do not risk permanently damaging your motor; get some cheap insurance with rocker arm stoppers.
